Detailed design of a base-isolated building as per Indian code provisions and practices is made and described here to facilitate corroboration of the design with other international codes and standards. Upon reviewing the latest developments and applications of the base isolation technology in India, the code development is presented. Particularly, the code provisions and practices in India have been elaborated in light of the state-of-the-art and state-of-the-practice. Then, by taking an example building, base isolation system has been designed and provided to achieve higher seismic performance. Assessment of the design outcomes is made to understand the implications of the code recommendation, especially from techno-economics viewpoints.
